United States EMULSION SPLASH GUARD FOR WINDING MACHINES Alice E. Watson and Ralph M. Willard, Philadelphia, Pa. Application August 28, 1956, Serial No. 606,682 6 Claims. (Cl. 118-123) bobbins or tubes, it is customary to provide an emulsion trough for applying an emulsion to the yarn to facilitate the subsequent handling by textile machinery and the like. In such conventional machines however, the yarn after passing about the emulsion roller is vibrated or shaken during its passage to the eye or other guiding device for directing the winding of the yarn upon a spool or on a cone, resulting in splattering any excess emulsion upon the yarn across the face of the machine. This is undesirable both from the standpoint of the cleanliness and resultant satisfactory operation of the machine, as well as from the aspect of wasting of the emulsion. l-leretofore, splash or drain aprons have been provided for returning such splattered emulsion to the emulsion trough, but owing to the large number of yarn ends and the emulsion trough through which each passes, such splash aprons cannot be uniformly successful.

Accordingly, it is a prime purpose of this invention to provide a device which may be easily applied as an attachment to existing conventional winding machines for winding yarn into cones or tubes, and which will more effectively prevent splashing of the emulsion with which the yarn is treated.

A further object of the invention is to provide an apparatus to facilitate the maintenance of yarn winding machines in a cleaned condition by preventing splashing of the machine by the liquid when the yarn passes over the emulsion roller of the mechanism and by reducing lint accumulated upon the emulsion splashed machine.

A further object of the invention is to prevent the wasting of emulsion by splashing as the yarn passes over the emulsion roller and thereby economize in the use of the emulsion.

A still further purpose of the invention is to provide a device in accordance with the preceding objects which will serve as a tension device in handling the yarn thereby reducing the quantity of tension weights required in the conventional yarn winding machine.

An additional object of the invention is to provide a device according to the foregoing objects which shall be of very simple and foolproof construction, inexpensive in its construction, durable and efiicient in operation and readily applied to conventional types of winding machines.

A final important object of the invention to be specifically enumerated herein, is to provide an attachment in compliance with the preceding objects which shall be readily mounted upon the emulsion apron of a yarn atent i 2,832,316 C Patented Apr. 29, 1958 winding machine and which may be conveniently pivoted into and out of its operative position.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accom panying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a view in vertical section showing an emulsion trough and emulsion applying roller together with the drain apron of a conventional yarn winding machine and to which the splash preventing attachment of this invention has been applied;

Figure 2 is a perspective view of the emulsion splash guard of this invention;

Figure 3 is a perspective view of the attachment looking at the opposite end and side from that of Figure 2;

Figure 4 is a perspective view of the splash bar of the attachment; and

Figure 5 is a detailed view in vertical transverse section taken substantially upon the plane indicated by the section line 55 of Figure 2 showing the reduced tension position of the splash bar in full lines and the increased tension positions of the splash bar in dotted lines therein.

Referring now first to Figure l for an explanation for a manner in which the attachment of this invention is applied to a conventional yarn winding machine, it will be observed that the numeral 10 indicates the conventional splash trough in which an emulsion applying roller 12 is mounted for rotation, while the numeral 14 indicates a conventional splash apron having at its lower end a downturned lip 16 which extends downwardly into the trough. This apron is provided with the customary side walls 18, and is adapted to be pivotally mounted as by apertures 20 in the upper ends of the side walls whereby the apron may be raised out of its operative position and lowered into as desired.

Also shown in Figure 1 as other conventional parts of the yarn winding machine are a hold-down roller 22 together with bar 24 carried by the arm 26 and forming part of a conventional form of stop motion for the wind ing machine which will discontinue operation of the same upon breakage of a yarn. Indicated by the numeral 28 is a yarn which during operation of the winding machine is drawn from any suitable source, passes over the bar 24- of the stop motion device, beneath the holddown bar 22, and then passes over the top of the emulsion applying roller 12, and from thence passes above the bottom wall constituting the apron 14 to the guiding eyes or other mechanism, not shown, and by which the yarn after treatment by the emulsion is wound into cones or upon spools, tubes or bobbins.

Referring now more specifically to Figures 2-4 it will be seen that the emulsion splash guard forming an attachment for the conventional winding machine described hereinbefore, is indicated generally by the numeral fit and comprises an elongated member 32. As will be best apparent from Figures 2 and 5, one end of this member is generally cylindrical in cross-section and. is provided with a longitudinally extending bore 34 and a pair of setscrews 36 are screw threadedly engaged in the mernber and intersectable for a purpose to be subsequently set forth.

Extending longitudinally of the member 32 is a substantially diametrically disposed slot 3% which as shown in Figure 1 is adapted to receive and embrace the downturned lip of apron l4, suitable fastening screws being carried by the member and extending into the slot for clampingly engaging the lip 16 thereby retaining the member thereon.

Referring now especially to Figure 4 it will be seen that there is provided a splash bar designated generally by the numeral 44 and which comprises a rod-like member 46 having at one end an angulated terminal portion 48 and at its other end being provided with an inturned portion 50 connected at the main portion of the bar as by the perpendicular section 52. The end portion 52 constitutes a crank which is adapted to be received in the slot 34, as shown inFigure 5, whereby the bar 44 is adapted to have arcuate oscillation about the portion 59 as will be readily apparent from a comparison of the full and dotted line showings of Figure 5.

It will be observed that there is an inclined plane face 54 extending the full length of the member 32 and sloping downwardly from one edge of the slot 38 upon that side of the member which faces the emulsion roller 12. This face provides a clearance whereby the bar may be oscillated about the axis of the portion 50, and when so oscillated whereby the bar 44 will clear the surface of the member 32 as will be seen from the dotted and full line showings of Figures 1 and 5.

It will be further seen that the major portion of the length of the member 32 upon the opposite side thereof from the plate face 54 is cut away to provide a plain surface 54 whereby the setscrews 40 will not protrude beyond the surface of the member 32.

The operation of the device is as follows:

With the parts arranged as shown in Figure l, yarn is passed from the emulsion roller 12 beneath the splash bar 46 and the latter is adjusted as shown in full and dotted lines in Figure 5. The yarn 28 thus passses over the emulsion applying roller 12 and the splash bar as, which holds the yarn downwardly against the apron 14, and serves to wipe excess emulsion from the yarn passing therebeneath, and to prevent vibration of the yarn against the apron 14 with the resultant splashing of emulsion. As the bar is raised the tension upon the yarn is decreased and lowering the bar adjustably increases yarn tension.

When it is desired not to use the splash bar, the yarn as it comes from the emulsion roller 12 is not threaded under the splash bar 46 but passes directly to the apron 14.

It will be noted that in addition to serving as a means for wiping excess emulsion from the yarn and preventing whipping or vibrating of the yarn against the apron, the bar also acts as a tensioning means to apply further tension to the yarn and thereby reduces the amount of weights required to tension the yarn.

The angulated end portion 48 of the splash bar extending beyond the member 32 acts as a guide means to facilitate insertion of the end of the yarn beneath the splash bar.

It will thus be apparent that there has been provided an attachment which may be readily applied to existing types of conventional yarn Winding machines, is unobtrusively mounted thereon, and is effective to reduce or completely eliminate the splashing of emulsion by the yarn upon the machine and will further act as a means to additionally tension the yarn during its travel from the emulsion roller to the guiding eye of the winding machine.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
